MariaDB 5.5.27 is a Stable (GA) release. In general this means that there are no known serious bugs, except for those marked as feature requests, that no bugs were fixed since last release that caused a notable code changes, and that we believe the code is ready for general usage (based on bug inflow).

For a description of MariaDB 5.5 see the What is MariaDB 5.5 page.

In most respects MariaDB will work exactly as MySQL: all commands, interfaces, libraries and APIs that exist in MySQL also exist in MariaDB.

Alternative Linux binaries

In this version of MariaDB we are starting to provide alternative Linux binaries built on a different build machine with a different build toolchain. Binaries created on this box require at least GLIBC_2.14. For continuity, we are still providing binaries built with the same toolchain as previous releases. The alternative binaries have a "(GLIBC_2.14)" label to distinguish them from the others.

Fixes and Performance Enhancements

This release includes fixes for the following security vulnerabilities:

This release fixes numerous cases of the incorrect identifier quoting in the replication code. They were open SQL injection vulnerabilities, that allowed, to a certain extent, to bypass the database privilege system and modify the data, that one was granted no access to. See MDEV-382 for details. (CVE-2012-4414)

Additionally, 5.5.27 includes several other bug fixes and performance enhancements.

See the MariaDB 5.5.27 Changelog for full details.
